My gen4 G17 fits my hand perfectly, with the standard backstrap. The gen 3 and 4 G19 models don't feel right in my hand though. The grips are too stumpy and my fingers don't line up in the finger grooves correctly. That's actually part of the reason I went with a CZ carry pistol, since the G19 is the equivalent size, caliber, and capacity of Glock... the CZ fits my hand better. I'm hopeful that the new gen 5 without finger grooves might fit my hand better. I know some people just sand the finger grooves off of their Glocks, but I'm not really into mangling my firearms like that.
) a gen 3 G17? It looks professional. Did you have someone local do that for you?
